Abstract (en)
[origin: EP4170307A1] A pressure sensor and an electronic device are disclosed. The pressure sensor includes a flexible printed circuit board (110) and multiple pressure sensitive adhesive resistors. The multiple pressure sensitive adhesive resistors include pressure sensitive adhesive resistors R1, R2, R3, R4, R5, and R6. The flexible printed circuit board (110) includes a first surface (A) and a second surface (B) that are opposite each other. The pressure sensitive adhesive resistors R1, R3, and R5 are disposed on the first surface (A), and the pressure sensitive adhesive resistors R2, R4, and R6 are disposed on the second surface (B). The flexible printed circuit board (110) is provided with a through hole (C) that allows the first surface (A) to communicate with the second surface (B), and the through hole (C) is at least partially covered by the pressure sensitive adhesive resistors R1, R2, R3, and R4. The pressure sensitive adhesive resistors R1, R2, R5, and R6 are electrically connected to form a first Wheatstone bridge, and the pressure sensitive adhesive resistors R3, R4, R5, and R6 are electrically connected to form a second Wheatstone bridge.
